T 0 all whom it may concern.

Be it known that I, FRANK POWELL, of West New York, county of Bergen,State of New Jersey, have invented certain new and useful Improvementsin Apparatus for Molding and Piercing Soles, of which the following is afull, clear, and exact specification, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an apparatus which makes it possible by a singleoperation, to mold or shape the soles of shoes and to pierce the samefor the reception of headed nails, as usually employed in heavy shoesintended for use by miners and other persons engaged in rough work.

My invention involves various other features of importance, all of whichwill be set forth hereinafter and particularly pointed out in the claim.

Reference is had to the accompanying drawing which represents a verticalsection of an apparatus embodying my invention, the drawing showing thesole in place in the mold and the top die member in position to descend.

In practice, the invention is embodied in a suitable machine operatedeither manually or by machine power, but I have not illustrated thismachine in the drawings since it will be fully understood by personsskilled in the art.

In the drawing, 6: indicates the bed plate or stationary part of such amachine, and Z) a plunger shaft adapted to be connected with suitabledevices by which it may be raised and lowered.

0 indicates the lower or female section of the sole mold which has onits outer surface the configuration corresponding to that which it isdesired to impart to the sole.

6 indicates the sole which is shown lying in the mold section 0,- and (Zindicates the male section which is attached to the plunger 5 and movestherewith.

In operation, the sole is inserted between the mold sections and theplunger 6 descends pressing the sole and giving it the configuration ofthe mold. For this purpose it is usual to wet the sole so that it willreadily take the shape imparted to it.

The mold section 0 is supported by springs f on a block composed of twosuperimposed parts 9 and k.

2' indicates stud bolts which limit the upward movement of the moldsection 0 restraining the action of the springs f within certain limits.

The two sections f/ and h of the block are removably fastened togetherby screws or the like is, while the lower section it is fastened bybolts Z to the before described bed or stationary part a of the machine.The engaging surfaces of the parts 9 and h of the block have aconfiguration corresponding to the configuration of the face of the moldsection 0 and fitted in vertical openings in the section 9 area numberof pins or needles m having slightly enlarged ends m which lie at theunder surface of the section 9 of the block. The pins m also looselyextend through openings in the mold section 0 and the parts f and 2' areso adjusted that when the machine is in inactive position the points ofthe needles m lie flush with the molded surface of the section 0. Itwill be observed that, owing to the fact of the needles 9% resting onthe curved upper surface of the section it of the block which uppersurface corresponds to the grooved upper surface of the mold section 0,the points of the needles follow the contour of the face of the moldsection 0 although the needles are all of the same length.

When the sole 6 is inserted in the machine and the mold section cZdepressed, the sole is molded into its necessary shape as beforedescribed, and as the pressure is exerted on the mold section 0, springsf give and the mold section drops until it engages and is arrested bythe top member 9 of the block. This causes the points of the pins orneedles m to project beyond the face ofthe mold and to enter the soleand pierce them for the reception of the hob nails. Upon the return fthe plungcr b and the mold section (7, the springs f return the moldsection 0 to the position shown in the drawings and the sole isdisengaged from the needles and may be easily removed from the machine.It will thus appear that by a single operation, the soles are molded andpierced. The needles may be in any desired arrangement, piercing thesole regularly or irregularly, as desired. It will also appear thatshould one of the needles become broken, the damage may be easilyrepaired by releasing the screws 70 and lifting the section 9 of theblock from its seat on the section 71. Thereupon, the

broken needle may be removed and a new needle inserted. The needles areuniform in length and size, thus adapting the machine readily to repair,and avoiding the necessity of manufacturing a number of needlesdiffering only in size and form.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

In an apparatus for molding and piercing soles the combination with maleand female sections the contiguous faces of which are shaped to theconfiguration which it is desired to impart to the sole, and means forimparting relative movement to said sections, of a supporting block forthe female section of said mold formed of two superimposed sect-ionsseparately connected, the contiguous faces of said block sections beingshaped to correspond to the shape of the contiguous faces of the moldsections, the female section and the upper sect-i011 of said supportingblock having registering openings, a plurality of headed needles ofuniform length arranged in the openings of said upper block section andloosely received by the openings of said female mold section, the headsof said needles being seated upon the lower section of the supportingFRANK POWVELL.
